Practical playbooks
Follow one of two focused paths: choose, build, and audit agent instructions; or diagnose, secure, and govern MCP access.
Choose AGENTS.md, CLAUDE.md, Copilot instructions, or Cursor rules Start with the current support matrix, then maintain one shared policy with small tool-specific adapters.
Fix an MCP server that is connected but shows no tools Use the interactive fault tree and minimal tools/list reproduction before changing permissions.
Build an AGENTS.md template for Codex Generate a Node.js, Python, or monorepo starter with setup, verification, boundaries, and proof-of-done rules.
Check whether GitHub Copilot reads CLAUDE.md Use the surface-specific answer for IDE Chat, cloud agent, code review, and Copilot CLI.
Audit MCP authentication, permissions, and revocation Apply the source-backed security controls before an agent receives credentials or write access.
Review Cursor Enterprise security and Privacy Mode Verify current retention caveats, group policy, model controls, MCP access, and contract evidence.
Audit an instruction file in the browser Check setup, tests, scope, safety, and path compatibility without uploading repository content.
